Automatic start arrangement for carburettors

摘要

Arrangement which is particularly applicable for use in two-stroke engines. The arrangement uses the starter conduit of the carburettor in order to incorporate, in a radial perforation transverse to it, a closure member which is forced to move longitudinally in the perforation in order to prevent or to allow the passage of a quantity of auxiliary mixture towards the engine in accordance with the supplies required by the latter at different operating speeds. This closure member also consists of a first piston of a depressor valve which activates the arrangement. <IMAGE>
